STRJCIURAL SURFACE FOP, REG-IVENG iND HGLDIN 'PLASTEB.

To all whom it may conce-rn:

Be it lnon' 'that l, Airriiin lli/Hirn, re-

Yented new and iiset'iil improvements in Structural `Surfaces for Receiving and Holding Plaster, of which' the following is a de` 4plastic plaster, or analogens` adhering` plast ic material, is applied to walls. That the euitace is especially adapted tor walls, does not Y d A i detract troni its \alue ano adaptation tor use in any place or position where plast er or adhering material is employed.

The invention consists oi the improved structural surt'aee as herein described and claimed, or the equivalents tl'iereot. l

My improved structural surface for holding )laster may be iii a inolded building block or brick o r tile, or may be in any other cliai'aetei'of building material; that is, it may be in any character ot' earthen ware, or metal, or wool, or any material capable of being formed into the Structural surface character embodying my invention.

lllliile iny structural surface may be inost eonveniently and successfully formed of earthen Ware, that is, of a brick, tile, COnerete or analogous iiiaterial, still it may be ot' any other material capable oit being used tor suoli plaster-holding surface.

ln the forin illustrated in the drawings, there welbuilding blocks A, A, the body or back o tv which has ribs or tongues 2, WithA alternating grooves 3 extending across the' block preferably longitudinally in the direction that: will be horizontal when the blocks are laid up in the Wall ot the building. These. tongues 2 may, as shown in l and Q, project. in diagonal or oblique directions t'ion'i the body of the block, thc grooves 3 going obliquely inwardly so as to undereut the tongues, as clearly shown in Fig. 2. 'llius when tlie'bloeks are in position in a vertical wall the grooves will extend down- .'ardly ii'iiardly, 'loin'iing suspending and holding hooks for the plaster.

While. the diagonal or oblique disposition ot the tongues and grooves as shown in several lign is deemed inost desirable, yet tongues i nii-jl grooves 5 disposedat right anp to the body ot the structure, as shown in .Home ot the iniguns would be quite Within the scope ot' my in rentionl Through each tongue there ie i'iluialit:;i apertures G, always departing from vthe groove on one side, usually extending to the groove on the he tongue, tliougl'i under some ariiiertures may extend roin one si Y, to the exterior surface 1e tongue.y shown at 7. These apertires ..init the passage of the inoitar liroiigli tnein when, in plastic condition, it

- plaster on the structural surface, the plaster by these lingers or tie-bars through the apertures in the tongues is securely and permanently anchored or held in place on the structural surface'or wall. The method of the attachment of the plaster to this surface is shown at B in Fig. 2. These linger or tie-bar apertures may be of any selected form, as for illustration round, oval, square, oblong or truncated-pyramidal as shown in the drawings; and with reference' to position through the tongue may be at or near its base, or interl'nediate of the base and the outer edge of the tongue, and maypass through the tongue at right angles to its walls, or oblique thereto, which positions and dispositions of the apertures are shown in the drawings in a few suoli forms and larrangements, these being quite sulicient to i any other similar and equivalent forms/,for sijch apertures. Also the apertures inlay be arranged in alinement longigitudinally of the tongues, as in Figs. l, 14, lo', 1.8 and 20, or may be in non-alinement as indicated in Figs. i", 8, 9, l0, l1 and 13. The purpose and method of operation of the apertures, for receiving fingers or tiebars of mortar and holding the plaster to the structural surface will be substantially the same in all cases.

lt should be understood that while my invention of a structural surface is stated herein to be adapted for taking and holding mortar and the plaster that results from the setting or hardening of the mortar, and is called a plaster-holding surface, it is as well adapted for, and the description is intended to include its use for, taking and holding cement, stucco or any and all other wall-making materials that are applied, While in a plastic condition to a holding surface, and that lset or harden into a rigid and permanent outer coat. of the wall.

W hat l claim as my invention is:

l. in combination lwith a building block adapted to be built with duplicate blocks into and form a wall of a building, a structural sun-.aco for receiving and holding surface-forming material comprising projec-Y tions n a series of parallel and adjacent lines on and across the face of the block and .integral therewith, the projections being provided with aperturesl through them laterally adapted to permit of the passage of soft plastic surface; forming material through them and allowing the portion thereof comino` from opposite sides of the projections to interiningle and r-dhere forining when the material has se' interlocking bars of the s material through the apertures and clasping the projections.

2. In combination With a building block adapted to be built with duplicate blocks into and-forni a Wall of a building, a structural surface for receiving and holding surface-forming material, comprising projections in a series of adjacent lines on and across theface of the block and integral therewith, the projections being provided with apertures through them laterally adapted to permit of the passage of soft, plastic surface-forming material through them and allowing the portions thereof coming from opposite sides of the projections to intermingle and adhere forming when the material has set integral vrigid interlocking bars of the `surface-formiug material through the apertures and clasping the projections.

ln combination with a building block adapted to be built with duplicate blocks into and form a wall of a building, a structural surface for receiving and holding surface-forming material, comprising oblique projections in a series of adjacent lines on and across the face of the block and integral therewith, the projections being provided withapertures through them later-l ally adapted to permit Aof the passage of soft plastic surface-forming material through them and' allowing the portions thereof coming .from opposite sides of the projections to intermingle 4and-'adluere forniing when the material has set integral rigid interlocking bars of the surface-forming material through the apertures and clasping the projections.

LA Wall constructed of building blocks each block having a series of adjacent surface-holding projections on and across the face thereof the projections having ,apertures laterally through them, and a surfacing material originally applied to the faces of the blocks 'in plastic condition covering the surface thereof and entering between and clasping the lprojections and passing entirely through and adhering together in the apertures in each projection severally forining when set rigid integral bars of the surface-forming material integral with the material between the projections on the blocks and bearing against and clasping the proj ections on and along the walls of the apertures and through the apertures.

In testimony whereof, l' alix my signature, in presence of two witnesses.
